New 6950 Display pot and HDMI slot 1 does not work

No matter which monitor i plug into the #1 display whether HDMI cable or Display Link it will not detect it. I have switched out all three monitors and they all work on display port 2 & 3 but not 1.

Hello Aaron,

Thank you for reaching out to us directly and providing your Amazon order ID number. That is much appreciated.

When you have a moment, could you please collect a set of diagnostic logs generated by our PlugDebug utility? It will gather device information and installation logs that will help our support team understand what could be happening. To collect these logs, please have your UD-6950PDZ plugged into your computer, and please follow this link for instructions:

The tool will collect system logs into a ZIP file and save them to your Desktop so they can be attached to your email reply. These log files combined with the problem description you’ve provided will help us understand what’s happening and provide the best next steps.

We look forward to your reply.
